INTRODUCTION

1.1Project Background

[image:13.595.88.527.455.606.2]

Wind power is generated by moving air. As the sun heats the land, the air above also warms and rises. Cold air then replaces the rising air. This creates the winds that we feel most days of the year. The diagram below shows how this ‘system’ works. Air tends to warm at a faster rate over land because the land retains its heat. Over the sea the air warms more slowly as heated by the sun and slowly cooled by the cold water. If you visit the seaside or coastal area you will probably find that the weather is more breezy or windy than inland. This is because the warm air rises over the land and cold air over the sea replaces it.

support for our life. Large wind turbine technology is already one of the larger future energy supplies and small wind turbines have a big potential. What is needed for a

common use of wind are turbines that meet a specification that is flexible enough for general application and be possible to mount almost everywhere and plug-in to the grid. Wind turbines on the market are often larger, mounted on high towers and need plenty of space around them for safety and efficiency. The only way is therefore to specify flexible wind turbines which need a small space, cheap, low risk to install and high efficiency.

1.2Problem Statement

Due to the wind is one of the renewable energy that have a high potiential to be developed as a source of electrical energy. In addition, wind energy can reduce greenhouse effect when its compared with other sources of electricity such as hydro, coal, gas plant or other renewable energy that can be use to generate an electrical energy. This project about the development a small wind energy converter consists of DC motor as a wind turbine, lcd display(to measure a voltage in the power storage) and the arduino uno board that located in a support curcuit. This project has been devolep because the wind energy has a high potential and the small wind energy require a the detail development because it has high potential to be developed in our country.

1.3Objective

The objective of this project is to build a small wind turbine which produce a rated power(1 Watt – 5 Watt) and to built a support systems using arduino controller for

emergency situation (if there is zero wind).

1.5Significant Of The Study

The overall study is about how to build the small wind energy converter with the support circuit that will make sure there are always has a supply from the turbine to the power storage. In this study the battery is used in the prototype small wind energy converter as a power storage. The support system was build using the arduino board and the computer as a host to control the input level to the turbine. In case there are no primary source to rotate the turbine, the input level speed for turbine will be control by the webserver that located in the computer and then the speed will be sent to the arduino board. Then , the arduino board will control the speed of turbine in order to generate electricity at the output terminal. Althought the support system use a small power to run the circuit system but the support system will provide a huge power to the turbine and it will produce a large power at the power storageThis systems has a high

LITERATURE REVIEW

2.1 Introduction

Wind is one of the renewable energy that can be used to produce electricity. The using of wind as a source to generate a electric energy become more significant nowadays. There are a lot of the benefit by using a wind as a main source to produce electric. This chapter will study the recent development on small wind energy converter , their social and environment benefit and interconnection issues of distributed resources including wind power with electric power systems.

2.2 Wind Speed Prediction

A.Kusiak, et.al [1] agree that one of the important aspect in handling the wind turbine energy converter is wind speed prediction. Wind speed is an important thing that must be consider because the power produced by the wind converter is totally depend on the wind speed. Determining the power generated by wind turbine at future times is important for unit commitment planning and maintenance scheduling. Wind speed must be predicted to

(18)

2.3 Power Curve Of A Single Wind Turbine

Wind speed is the most influential factor on the power generated by a wind turbine. The theoritical power [2] that can be extracted from the wind is expresses by equation (1) :

P=0.5πR²Cp(λ,β)V³ (1)

Where P is the theoritical power captured by the rotor of a wind turbine, p is the air density, R is the radius of the rotor (blade’s length) determining its sweeping area, Cp(λ,β) is the power coefficient and V is the wind speed. The air density p at the turbine’s hub height remains usually constant over a long-time horizon. Thus the most important operation parameters impacting the generated power area Cp(λ,β) and V. The power coefficient indicates the efficiency of a turbine capturing the wind energy and its is optimized by the control system[3].

To analyze the perfomance of wind turbines, the SCADA data collected at a wind farm has been used. Table 2 shows data set 1 with the beginning time stamp “1/1/07 12:00AM” and ending time stamp “1/31/07 11:50 PM”. Data set 1was divided into two data subsets, data set 2 and data set 3. Data set 2 contains 3476 data points and was used to develop a data-driven model estimating the power curve. Data set 3 inlcudes 871 data points and was

[image:18.595.81.532.546.696.2]

used to test perfomance of the model learned from data 2.

power gain. The data points in region away from the logitic-curve region usually represent an anomaly leading to, for example, decrease perfomance[3].

2.4 Social And Economic Benefit Of Wind Energy Technology

Wind benefits brought by ( Resources, Energy and Tourism) RET have been extensively evaluated, as well as economic costs and its contribution to energy security. However, a thorough discussion of the socio-economic impacts of these technologies is still limited. This discussion becomes even more important in periods of low economic growth [4,5]. One of the the social and economic benefits are technological innovation and industrial development distributed generation and universal access to energy regional and local development, especially in rural areas and job creation. According to Laitner et al. [6], assessments on the performance of climate and energy policies usually do not take into account the dynamics of technological innovation, and often associate reductions in energy consumption and GHG emissions with economic losses.

Frankhauser et al. [4] argue that technological innovation and the creation of new opportunities for investments and economic growth are both consequences of climate policies. Technological change and innovation, in the long term, increase the demand for labour and skills. The writer also emphasize the role of good policies aimed at motivating technological innovation. In this context, the pioneers in the development of clean

technologies have the potential for regional leadership. The author also use the case of Germany, which today stands out as a leader in the export of clean technologies. RET are

meet the development goals without going through the intensity of fossil fuel consumption that marked the growth in developed countries [11]. The convergence between the fields of

energy planning and economic development is present in various energy policies. Such convergence is known as energy-based economic development, whose main goals are to increase self-sufficiency and energy diversification, contributing to economic and industrial growth and development; to increase entrepreneurship and encourage technological innovation; and to increase the level of employment and training [12]. The presence of renewable energy projects in rural areas, especially those characterized by low economic development, can bring benefits to the community. High unemployment rates, lack of alternative economic development, and high rates of migration of economically active population, offer a worthwhile environment for investment in RET. Compared to traditional power plants, renewable energy units are often smaller, modular and decentralized and, therefore, they are often located in rural areas with low population density. Due to this feature, the construction of these plants demands high amounts of labour, and creates the potential for training and employment of rural populations in several locations [13].

Besides generating temporary jobs in construction, there are fewer but long lasting job opportunities in the operation and maintenance (O&M) of power plants. The deployment of renewable energy projects offers an alternative or complement to agricultural activities,

development benefits brought by investment inrenewable energy sources is illustrated in Figure 2.

(22)

Jobs generated by wind power and other RET can be grouped into three part according

to their location, temporal nature, and level of expertise. The first part refers to jobs

[image:22.595.77.534.297.468.2]

generated in technological development, and includes R&D and equipment manufacturing. The second part refers to jobs in installation and decommissioning of plants, and comprises planning, project management, transportation and power plant construction and decommissioning. The third part is operation and maintenance (O&M), and includes, besides the actual O&M of the plant, energy distribution and commercialization. The characteristics are summarized in Table 3.
